Define Prophase I, Metaphase I, Anaphase I, Telophase I In a simple form

1).  Prophase: This known to be the first step of mitosis. This phase is denoted when genetic fibres within the cell nucleus known to be chromatin begins to condense and become tightly compacted together.

2). Metaphase: This is known to be the second stage that follows prophase and prometaphase and progrsses to anaphase. Metaphase starts to occur when once all the kinetochore microtubules get attached to the sister chromatid which is brought about by the force generated.

3). Anaphase: At this phase, the centomeres at the centre of the sister chromatids are severed. It ensures that each chromosome receives identical copies of the parent cell’s DNA.

4). Telophase: This is the last phase of mitosis. It occurs when the newly formed daughter chromosomes get their own individual nuclear membranes and identical sets of chromosomes.

The main purpose of mitosis is to accomplish cell regeneration, cell replacement, and growth in living organisms.
